Summary
Frontier Communications (EPIX)
isp legacy
FRONTIER-EPIX is held by Frontier Communications of America. The EPIX name is the giveaway: this network began as epix, the Eastern Pennsylvania Internet Exchange, an early Pennsylvania internet service that came to Frontier through its acquisition of Commonwealth Telephone.
What it's used for
- Broadband internet access for homes and businesses across Frontier's Pennsylvania and neighbouring service territory.
- Carries a substantial pool of IPv4 — well over a hundred thousand addresses spread across many prefixes, the usual shape of a subscriber-access network.
Notable
- An eyeball network: addresses here are handed to end customers, so an IP in this range is normally a residential or small-business subscriber rather than a server.
- Frontier operates several ASNs; this one carries the legacy epix footprint rather than the whole company.
Interesting
- epix was one of the earliest internet services in Pennsylvania, launched by a local telephone company in the mid-1990s and growing into a dial-up ISP with tens of thousands of customers before the telco consolidations that eventually put it inside Frontier.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 446 networks and 1,852 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
